Ok, firstly, thank you all for putting up with me and all your awesome help.
Managed to download that file, unzip to folder, run and install.
Seemed to do all it needed to and finished with "press any key" as instructions showed so must have been good.
UPDATE: lol sorry, my son now says he is playing on Steam f2p with him mates (dad crawls away) so I now have one last question.
I have installed the Akkas PEQ server and files etc, but now want to just configure to single player, no one else to join, would you please be kind enough to let me know what I should change to make it just a single player server.
I know im a pain, but im so desperate to relive my old game once more
